fix: auto-save report after clean() completes in GUI and CLI

- Add save_report parameter to DiscreteMaterialPlanCleaner (default True)
- Auto-save report at end of clean() method when save_report_enabled
- Remove explicit save_report() call from main() (now automatic)
- Pass save_report=True in GUI _delete_worker()

This ensures reports are saved for both GUI and CLI execution paths.
